Bierbaum, Lauren J.; Henrich, Christopher C.; Zigler, Edward F. – Journal of Intellectual and Developmental Disability, 2005
Background: Teacher reports of disobedient behaviours in children with intellectual disability noted in previous investigations represent a mismatch with the typical personality profile associated with intellectual disability. We hypothesise that this contradiction arises from the frustration experienced by children with intellectual disability…

Rupela, V.; Manjula, R. – Clinical Linguistics & Phonetics, 2007
Phonotactic patterns of seven 11-15-year-old Kannada speaking children with Down syndrome (DS), mental age matched children with mental retardation (MR) without DS and six 4-5-year-old typically developing (TD) children were investigated. Conversational speech analyses and target analyses of conversational speech were carried out in all three…

Background: Effective literacy skills are crucial in supporting communication for children with severe speech and physical impairments (SSPI). Reading and spelling difficulties are reported to be over-represented in this group, even where language and cognitive skills are age appropriate. Aims: To compare the performance of children with SSPI on a…

Vicari, S.; Verucci, L.; Carlesimo, G. A. – Journal of Intellectual Disability Research, 2007
Background: In the last few years, experimental data have been reported on differences in implicit memory processes of genetically distinct groups of individuals with Intellectual Disability (ID). These evidences are relevant for the more general debate on supposed asynchrony of cognitive maturation in children with abnormal brain development.…

This study investigates the syntactic abilities of ten individuals with Williams syndrome (WS) (mean chronological age: 8;9 years; mean mental age: 4;8 years) and Down's syndrome (DS) (mean chronological age: 8;7 years; mean mental age: 4;6 years), matched individually on chronological age, mental age and performance IQ. The syntactic components…

Dickson, Chata A.; Deutsch, Curtis K.; Wang, Sharon S.; Dube, William V. – American Journal on Mental Retardation, 2006
A delayed matching-to-sample task with multiple sample stimuli was used to evaluate stimulus overselectivity in 70 individuals attending residential special-education schools. A Mental Age Equivalent score (MAE) was obtained for each student using the Peabody Picture Vocabulary Test. Twenty-one participants failed to complete matching-to-sample…

Lorusso, M. L.; Galli, R.; Libera, L.; Gagliardi, C.; Borgatti, R.; Hollebrandse, B. – Clinical Linguistics & Phonetics, 2007
It is a matter of debate whether the development of theory of mind (ToM) depends on linguistic development or is, rather, an expression of cognitive development. The study of genetic syndromes, which are characterized by intellectual impairment as well as by different linguistic profiles, may provide useful information with respect to this issue.…

Luyster, Rhiannon; Lopez, Kristina; Lord, Catherine – Journal of Child Language, 2007
Characterizing early communicative development in children with Autism Spectrum Disorders (ASD) is valuable for understanding profiles of ability in this population. The current investigation was modeled on Charman, Drew, Baird & Baird (2003b). Analyses explored parent report of early vocabulary, non-verbal communication, functional object use and…

Lukose, Sara – 1983
Twenty mildly mentally retarded students were matched with two groups of normal students, one of the same chronological age (CA) and one of the same mental age (MA), to examine the influence of age indices and metamemory on memory behavior in terms of recall accuracy and recall time. This was achieved using a metamemory instrument which was…

Mervis, Carolyn B.; Klein-Tasman, Bonita P. – Journal of Autism and Developmental Disorders, 2004
Group-matching designs are commonly used to identify the diagnosis-specific characteristics of children with developmental disabilities. In this paper, we address three issues central to the use of this design. The first concerns the alpha level to be used for considering groups to be matched on the control variable(s). The second involves the…

Goodstone, Judith L.; Whittemore, Charles – 1983
In an investigation of social inference (the ability to decode and comprehend cues), prompt questions of decreasing cognitive complexity were employed to train 60 mildly mentally retarded adolescents to logically interpret pictorial stimuli. Cartoon line drawings were used illustrating social situations representing a variety of family and peer…
